Depression MildDepression Moderate2 more

The primary objective will be to study changes in putamen connectivity and depression severity in depressed teens with meditation training. H1: Putamen node strength will increase in the training group compared to the active controls. H2: This increase in node strength will correlate with practice amount recorded by participants. H3: There will be a significant reduction in self-rated depression symptoms following the training as measured by the Reynolds Adolescent Depression Scale (RADS-2), compared to controls. H4: This reduction will correlate with the increase in putamen node strength. Design and Outcomes: The current research study design will utilize an individually randomized group treatment, open-label, active-controlled clinical trial to test the efficacy and safety of the investigator's innovative mindfulness meditation intervention (Training for Awareness Resilience and Action [TARA]) on the primary outcome (Putamen structural node strength) and secondary outcome (depression symptoms measured using Reynolds Adolescent Depression Scale [RADS-2]) in depressed adolescents between the ages of 14 to 18 years old.

Food for Mind - Intervention in the Treatment of Depression

Depression

Aims. The main aim of the study is to explore whether Food for Mind - Group-based behavioral nutrition intervention alleviates depression symptoms. Furthermore, we aim to investigate, whether the intervention improves the quality of diet, eating habits, quality of life, ability to work and to study its cost-effectiveness. In collaboration with 11 public and private health care service providers in cities of Kuopio and Siilinjärvi in Northern Savo, Finland. Participants. The total number of subjects will be 144 based on power calculations. The calculation is based on the clinical decline of seven points assessed by the Center for Epidemiologic Studies Depression (CES-D) Scale. Participants sign an informed consent form to participate Food for Mind - intervention. Study design. In this randomized controlled clinical trial subjects are randomized into two parallel groups: Food for Mind -behavioral nutrition intervention group (n=72) and Group to bring Good Mood -control group (n=72). The intervention consists of behavioral nutrition counselling (5 times 1½ h and 1 time 3 h) and the control group (befriending group) (n=72) (5 times 1½ h and 1 time 3 h). Thus, in the befriending group the same visit schedule and length without any nutrition counselling is used. The befriending group consists of discussion of neutral topics, like hobbies, music, sports, and doing together. Both groups continue to have their normal depression care in the health care. Enrollment and treatment will take about four years, and follow-up will last about one year. The Northern Savo Hospital District Committee on Research Ethics gave its consent to the study protocol. Methods. All questionnaires are validated. CES-D -depression scale, Seasonal Pattern Assessment Questionnaire, The Diet Quality Index (IDQ), Diet frequency -questionnaire, Eating competence -questionnaire (ecSI 2.0), The Three Factor Eating Questionnaire, Ability to work and function -questionnaires, Assessment of Quality of Life (AQoL)-8D (8 dimensions) -questionnaire, Treatment expectancy -questionnaire, Acceptability -questioinnaire. In addition, body composition measurement and cost-effectiveness analyses to evaluate the health outcomes in relation to resource utilization and costs in Food for Mind -intervention.

Mechanism of Action Underlying Ketamine's Antidepressant Effects: The AMPA Throughput Theory in...

DepressionMajor Depressive Disorder1 more

Background: Most drugs that treat mood disorders take a long time to work. Ketamine works within hours. A dose can last for a week or more. Certain receptors in the brain might help ketamine work. A drug that blocks these receptors might affect how it works. Objective: To see if the antidepressant response of ketamine is linked to AMPA receptors. Eligibility: Adults ages 18-70 with major depression disorder without psychotic features Design: Participants will be screened under protocol 01-M-0254. They will have blood tests and a physical exam. Participants will stay at the NIH Clinical Center for 5 weeks. Phase 1 lasts 4 weeks. For 2 weeks, participants will taper off their psychiatric medicine. Then they will have the following tests: Blood draws Psychological tests MRI: Participants will lie in a machine that takes pictures of their brain. MEG: Participants will lie down and do tasks. A cone lowered on their head will record brain activity. Optional sleep tests: Electrodes on the scalp and body and belts around the body will monitor participants while they sleep. Optional TMS: Participants will do tasks while a wire coil is held on their scalp. An electrical current will pass through the coil that affects brain activity. For phase 2, on day 0 participants will take the study drug or a placebo orally. While having a MEG, they will get ketamine infused into a vein in one arm while blood is drawn from a vein in the other arm. On day 1, participants will again take the study drug or a placebo orally. On days 3-7, they will repeat many of the phase 1 tests. Days 8 and 9 are optional and include an open label ketamine treatment and many of the phase 1 tests.

Alleviating Stress by Mobile Application' for Depression

Major Depressive Disorder

This study is a single-blind, multicenter, randomized, controlled crossover trial. The App, developed in South Korea, is an application that provides integrated interventions for stress reduction for the general population. The App provides three contents based on MBSR, CBT, and relaxation sounds that are known to be effective in stress reduction ("Meditation category", "Cognitive approach", and "Relaxation Sound", respectively). Participants (n = 215) recruited via medical practitioner referral will be randomized to App first group (fAPP) or a waitlist crossover group (dAPP). Inclusion criteria are age 19-65; diagnosed with mild to moderate major depressive disorders (Score of 7-24 on the Hamilton Rating Scale for Depression); Stable medication for 28 days prior to study participation. The study was conducted over eight weeks, the fAPP group used The App for the first four weeks and the dAPP group for the next four weeks, and during all study periods, the participants received usual pharmacological treatment. Primary outcome measures are the Depression Anxiety Stress Scale-21. The analysis will use mixed-model repeated measures.

Reward Emotion Learning and Ketamine Study

DepressionMajor Depressive Disorder1 more

Ketamine's efficacy as an antidepressant is now well established yet the mechanisms underlying its antidepressant effect are yet to be fully described. Work in the animal literature and research in humans is suggestive of specific effects on anhedonia and memory reconsolidation. In this study the investigators will further explore the effects of ketamine on learning and memory as well as measuring the associated changes at neural level in a sample of healthy volunteers. Participants will be assigned to receive ketamine or placebo and complete a set of tasks which will allow the investigators to quantify the effect of ketamine on learning about reward and punishment and memory for learned reward associations 24 hours after ketamine infusion. This study will help the investigators to understand the basis of ketamine's antidepressant effects and aid the development of new treatments for depression.

eMBC for Perinatal Depression and Anxiety

DepressionPostpartum1 more

Depression and anxiety that occur around the time of pregnancy can adversely impact a person's health and well-being, and their child's health and development. Fewer than 20% of affected people are adequately treated, often because of under-use of medications. Measurement based care (MBC) is a model of care where psychiatric symptoms are routinely tracked and reviewed together by a patient and their doctor to better manage symptoms. It has not been systematically evaluated for perinatal depression and anxiety. The overall objective of this study is to test the feasibility of MBC in this population to inform a future large randomized controlled trial for definitive evaluation. In order to avoid known barriers to MBC, electronic MBC (eMBC) will be used. With eMBC, patients can enter their symptoms into their electronic medical records before their appointment so that they can be evaluated by their doctor during the appointment. In this pilot study, the feasibility of recruitment for a future efficacy trial, including feasibility of recruitment, and retention, acceptability and adherence to a trial protocol will be evaluated.

mHealth Intervention to Reduce Maternal Postnatal Depression and Promote Family Health

Postnatal DepressionQuality of Life1 more

The proposed study is to test the effectiveness of a culturally-attuned, family-based mobile health (mHealth) intervention in reducing symptoms of postnatal depression and promoting health among expectant mothers in Hong Kong. Using a family perspective, the proposed mHealth intervention will engage family members, including expectant fathers and grandparents, in providing support to expectant mothers. Expectant mothers and their family members will be recruited at antenatal clinics at two public hospitals in Hong Kong and randomized to receive the family-based mHealth intervention (experimental), the mother-only mHealth intervention (experimental), or the health education (control). Maternal depression, anxiety and stress, perceived social support, health-related quality of life, and perceived family cohesion will be assessed at recruitment and four weeks after childbirth. For family members, symptoms of anxiety and stress, health-related quality of life, and perceived family cohesion will be measured.

Low Intensity Focused Ultrasound: a New Paradigm for Depression and Anxiety

Depression

Objective: Preliminary studies show that low intensity focused ultrasound (LIFU), a new type of non invasive brain stimulation (NIBS), may be able to reach deep structures of the brain involved with depression and anxiety, that remain inaccessible using current forms of NIBS with precision. In this study, the investigators will test if this technique can be used to change brain activity in areas that are connected to depression and anxiety symptoms. The primary objectives of this study are to test the safety and tolerability of LIFU, evaluate the feasibility of using LIFU to reduce brain activity, and evaluate the feasibility of simultaneous fMRI-LIFU. If the results of this study are positive, what the investigators learn will serve as a strong foundation for the future development of innovative treatments for a variety of psychiatric disorders. Research Procedures: 25 patient and 25 healthy veterans will be recruited. Visits will take place at the VA Providence Healthcare System. During some visits, healthy and patient participants may undergo clinical and research neuroimaging, neuropsychological testing, complete questionnaires, and participate in clinical/neurological assessments. Healthy veterans will not receive LIFU and will only attend 2 study visits. Patients are expected to attend up to 8 visits over 6 weeks. However, some may require up to 6 extended follow-ups after visits 5 or 8, in which case they would attend a total of 11 or 14 visits over 6 months. Two patient visits will include the LIFU application, following FDA safety guidelines. Patients will be assigned either to an experiment in which LIFU stimulation will be delivered immediately prior to a task or to an experiment in which stimulation will be delivered during the task. Within each experiment, patients will be assigned to first receive either LIFU stimulation to the study target or anatomical control. Study staff, but not participants will know which location is being targeted in case safety concerns arise. Safety assessments will be conducted at follow-up visits. A clinician will be available during LIFU administration /follow-up visits. Assuming no injury or other concerns are present, patients will then repeat this process again, receiving stimulation targeting other brain area not previously selected.
